Hydromorphone , a more common synonym for dihydromorphinone and dimorphone , commonly a hydrochloride (trade names Palladone , Palladone SR , Dilaudid and numerous others (Warning: The brand names are inconsistent from country to country.)) is a potent centrally-acting analgesic drug of the opioid class; it is a derivative of morphine , specifically a hydrogenated ketone thereof?therefore a semi-synthetic drug and both an opiate and a true narcotic . It should not be confused with hydromorphinol , also known as 14-hydroxydihydromorphine and RAM-320 nor dihydromorphine (Paramorfan). While all of these are strong opioids, they are indeed different drugs. Additional confusion here comes from the fact that in a handful of countries hydromorphinol is distributed under the trade name Numorphan, which is the trade name for oxymorphone in the rest of the world according to the current version of The A-Z Encyclopaedia of Alcohol & Drug Abuse and other references. less
